Peer Reviewed Articles or Refereed articles

Peer review or refereeing is a process to ensure that the articles they publish include only the best erudition currently available. The articles submitted to a peer reviewed journal are sent out by editors to other scholars in the same field (or narrowly defined field) to obtain an impartial review on the quality of the scholarship, its relevance to the field, its appropriateness for the journal, etc.

Practically speaking, peer reviewed journals are considered as more reliable sources of information than others since peer review refers to the work done during the screening of submitted manuscripts and funding applications.

This process allows only authors to meet the standards of the magazine and dissuades unwarranted claims and personal points of view that cannot be corroborated.

Journals that do not follow this process cannot generally be counted on for solid, scientific scholarship.
